With the inner joint, try taking out the other side and using a long thin flat blade and a hammer from the back side. Has worked for me when I sheared the male end off at the track. Had nothing to grab a hold of, so had to use that method.

Sludgehammer works great also a torch would do the trick.. I know the dsm spindles get rusty inside and are close to impossible to get out.. If you can take it all off put it on something so you can get 1/2 good hits straight down at the top of it..
